This is an excellent question that I hope I can answer clearly for you. 68804 cubic meters are the dimensions.
Sorry about the wait...was calculating!
Answer:
225
Step-by-step explanation:
Mary = 3x (3 times Carey)
Carey = x
Barry = x/2 (Because Carey read twice as many as Barry, it means he read half the amount Carey did)
3x + x + x/2 = 405
4x + x/2 = 405
8x/2 + x/2 (treat these as fractions) = 405
9x/2 = 405
9x = 810 (cross multiply)
x = 90
Mary = 3(90) 270
Carey = 90
Barry = 90/2 45
Mary - Barry
270 - 45 = 225
Hope this helps! :)
Answer: I believe it would be 42 different ways.
Step-by-step explanation:
multiply the 7 and the 6 to determine it
Find the least common multiple of 8, 15, and 21. . . . . . It's 280 .
So all the numbers divisible by 8, 15, and 21 are all the multiples of 280.
The smallest 6-digit number is 100,000 .
100,000 / 280 = 357.1 , so the next whole-number multiple is the 358th one.
280 x 358 = <u>100,240</u> .
You can tell right away that this is the smallest one that qualifies,
because if you take away 280 and go to the next smaller multiple,
it won't have 6 digits anymore.
